IMPROVEMENT IN HOSE-NOZZLES.

Specification forming part of Letters Patent No. 177,478, dated May 16,1876; application filed April 26, 1876.

.on, to be a full, clear, and 'exact description of the same, and whichsaid drawings constitute part of this specification, and represent, in-

Figure 1, a side view; Fig. 2, a vertical central section; and in Fig.3,a detached view.

This invention relates to an improvement in the construction ofhoze-nozzles, the object being to .provide for cutting off or stoppingthe flow through the hose without the necessity of going to the hydrantor head. It 0011- sists in an india-rubber or elastic sleeve within thenozzle, combined with transverse slides working toward the center, so asto compress the sleeve and cause it to close the passage through thenozzle, all as'more fully hereinafter described. y

A represents the body of the nozzle; 13, the tip, which may be of any oftheknown constructions; G, the socket, by which thenozzle is attached tothe hose. a is an india-rubber or elastic sleeve (denoted in solid blacklines) arranged within the nozzle, and secured at its upper and lowerends. D is a collar, concentric with the nozzle, and arranged so as toturn freely.

stops the flow.

On this collar is. a flange, d, turned inward in a horizontal plane, andwith a thread cut on its surface in scroll form, and onto this threadedsurface [there is placed a pair of slides, E. upon opposite sides, theseslides, provided with ribs 6, (see Fig. 2,) corresponding to thescroll-thread or grooves on the flange at, so that by turning the collarD the slides E will be moved toward or from each other, according to thedirection of revolution of the collar D. These slides work through slotsf and against the surface of the sleeve a, and that sleeve, beingelastic, yields as the slides are forced against it, until broughtcompletely together, as indicated in broken lines, Fig. 2, which closesthe passage and Returning, the collar 1) will draw back the slides E andopen the passage.

The discharge may be regulated by means of these slides, if desired. Theprincipal object is to allow the cutting off of the flow by the personin charge of the pipe.

We claim In a hoze-nozzle, the combination of the elastic sleeve a, thescroll -threaded collar D, and the slides E, constructed and operatingsubstantially as specified.
